Upside down, right side up: It matters little to week-old harp seals, snug in mufflike coats of infant hair. Newborn pups weigh about 20 pounds. At three weeks they average 90 pounds, replace white coats with gray, and take to the water. Today, conservation quotas limit the take by sealers, who once slaughtered 100,000 ani mals a year in these waters. Helicopter pilot (left) nudges a pup toward a tagger; mother seal barks defiance. Whirring above sheet ice on the Gulf of St. Lawrence, airborne natural ists study migrations of herds and make head counts.
